Analogix 7625 can be used in systems to switch the DP traffic between
two downstreams, which can be USB Type-C DisplayPort alternate mode
lane or regular DisplayPort output ports.
Update the binding to accommodate this usage by introducing a
data-lanes and a mode-switch property on endpoints.
Also include the link to the product brief in the bindings.
